Which EMC (electromagnetic compatibility) devices are helpful for the design and modification of electric wheelchairs?

EMC design for electric wheelchairs is crucial for safety. The power MOSFET/IGBT bridge arms of the motor controller should have parallel RC snubber circuits, and the driver power supply should use high-current bead filtering. Control signal lines such as joysticks must use shielded cables and be filtered and optocoupled for isolation at the controller input. The entire metal frame should act as grounding and shielding, and the battery negative terminal should be reliably connected to the frame. To reduce radiation, the motor power lines can be twisted in pairs and possibly shielded with tubing. The system should have software interlocking and safety protection logic, and a hardware watchdog timer should reset the system even under strong interference.
